Are pecan trees self pollinating?
Pecan trees are cross-pollinated (allogamous) and although self-pollination is possible, the result is largely unsuccessful. Only one pollen grain is required to produce one pecan. One catkin can produce enough pollen to pollinate flowers to produce 50,000 pounds of average-sized pecans.
How many pecans can 1 tree produce?
A single pecan tree is capable of producing 50 lbs of nuts per tree in the 10th growing season and 100 pounds in the 15th growing season. Pecan trees are most frequently planted at densities ranging from 12 to 48 trees per acre, making it possible to produce over 1,000 pounds per acre per year.
How many varieties of pecan trees do you need?
Therefore, it is imperative that you consult a pecan variety pollination chart (learn more at www.noble.org/cross-pollination-is-essential) when designing a pecan orchard to ensure there will be adequate pollination. It is recommended to find at least two to three varieties that shed pollen at the same time the main variety is receptive.
Can you grow pecans in a small yard?
It’s not a tree that you can easily grow in a small yard. Like walnuts, pecans are messy trees. Through the year they will drop male flowers and sap everywhere. So if you don’t mind the mess, the trees will produce a wonderful harvest of buttery tasting nuts with easy-to-crack shells.
Do you have to cross pollinate pecan trees?
For adequate cross pollination between pecan trees, it is highly recommended you grow at least one of each type. Some pecan trees shed pollen first and their pistillate flowers are receptive of pollen later in the season. These varieties are referred to as Protandrous, having a ” Type I ” flowering habit.
Why do pecan trees have both male and female flowers?
Pecan trees are monoecious, meaning each tree has both male and female flowers. But you’ll need more than one variety for a good harvest, since the male and female flowers are receptive at different times on a single tree. The primary agent of pollination is wind, which allows pollen to blow from one tree to the flowers of another.
